We examined yearly variations in the past-year CUD prevalence (abuse, dependence) in the total adult sample and the conditional CUD prevalence among past-year cannabis users to gauge the population-level CUD prevalence and determine the likelihood of CUD given use by race/ethnicity. The latter provides information to inform prevention and intervention research. In the pooled sample, we determined racial/ethnic differences in the frequency of CU (monthly, weekly), cannabis abuse, and cannabis dependence to clarify CU patterns by race/ethnicity.
